Abstract: This invention relates to an improvement in driving performance of an electric car in which the driving wheels are driven by a motor. More specifically, the first feature of the present invention improves driving performance without making its mechanical construction complicated. The second feature of the present invention improves motion performance of the electric car by simplifying the structure of the steering wheels serving also as the driving wheels and improving freedom of the turning operation of the steering wheels. To accomplish these objects, in an electric car equipped with the driving wheels (2a, 2b, 3a, 3b) on both sides of the car body, the present invention disposes independently the driving motors (21a, 21b, 22a, 22b) for them, controls independently these motors and applies further this structure to the steering wheels.

Abstract: Arbre à came composite en plastique stabilisé et procédé de fabrication. Dans une version, un tube poli creux (75) est positionné dans des éléments de came annulaires fixés et alignés de manière appropriée (73) ayant des saillies intérieures (79) qui augmentent de taille vers l'axe du tube et un matériau coulant durcissable est injecté au travers du tube (75) pour remplir les vides existant entre le tube (75) et les éléments de came (73) pour fixer les éléments de came (73) au tube (75). Les saillies (79) améliorent la prise du matériau plastique avec le retrait. Les surfaces du tube (75) et des éléments de came (73) sont prérectifiés aux dimensions finales. Dans une autre version, les éléments de came annulaires sont à l'origine circulaires et prennent leur configuration finale dans le moule à l'aide de navettes agissant latéralement et ayant une configuration appropriée. Dans un mode préférentiel de réalisation pour des applications automobiles, l'arbre à came et les éléments de came présentent des configurations d'emboîtement qui forment un espace continu entre eux de sorte que le matériau durci résiste par compression aux forces de torsion entre l'arbre à came et les éléments de came. Un procédé de moulage par injection sans application de contrainte sur l'arbre à came supporté librement est également décrit.

Abstract: A method for improving the seismic resolution of geologic structures is disclosed. Refracted wave arrivals are gathered into common midpoint trace gathers. Data representations originating inside a critical offset distance are muted, and the remaining data is tau-P summed and projected into zero source-to-receiver offset. Constant velocity stacks can then be displayed. A plurality of common midpoint trace gathers can be used to generate multiple panels of tau-P sums. Portions of several of these panels can be combined to provide a complete image of the subsurface reactors. A near-surface velocity model can then be designed, to provide a solution to near-surface statics in seismic traces.

Abstract: A dough-stretching roller apparatus is provided to produce a continuous web of dough in a process to manufacture confectionery and bread. The apparatus includes a pair of upper rollers (3) and a pair of lower rollers (4), a sensor means (5) that measures the thickness of the dough when it enters the lower rollers, and a controller (11) that controls a motor (8) driving the upper rollers in response to a signal from the sensor means. The controller increases the rotational speed of the upper rollers when the sensors detect that the thickness of dough is less than a preset thickness and decreases such rotational speed when the thickness of the dough is greater than the preset thickness. Thus, even if the quantity of dough supplied from a hopper is unstable, the stable production of a stretched web of dough having a constant volume per unit length can be assured.
